["Choosing wisely" - mission and aims].

"Klug entscheiden" addresses the problem of over- and undersupply in medicine. Following the American model "Choosing wisely" an interdisciplinary team of all internal medicine societies develops evidence-based recommendations to improve the quality of indications. In contrast to guidelines, the initiative does not provide comprehensive medical recommendations, but focuses on problems that are particularly relevant to health care. In addition, it is intended to promote communication between doctors and patients, but also the national debate on the responsible and sensible use of medical resources.
